Follow-up Comment #1:

Thanks for your bug report. I believe the errors you are seeing are due to the
recent C++ ABI change in gcc, see
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html.

Try building Octave and/or Octave Forge packages with the 
_GLIBCXX_USE_CXX11_ABI macro set to 0. For example I now build Octave with


$ ../configure CPPFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0 ...


This is stored in Octave and passed along to subsequent builds of oct-files
using mkoctfile or pkg install. I do not have the undefined symbol errors you
are seeing with this macro defined.
